OIL-STOVE AND BURNER.

SPECIFICATION forming part of Letters Patent No. 513,713, dated January30, 1894.

Application filed March 6 1893- fierial No. 464,675. (No model.)

To whom it may concern.-

Be it known that ,I, EDWIN G. MUMMERY,

a citizen of the United States, residing at Detroit, county of Wayne,State of Michigan, have invented a certain new and useful Improvement inOil-Stoves and Burners; and I declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification;

My invention relates to certain new and useful improvements in an oilheating stove, and in a novel construction of a burner to be used inconnection therewith. My improved burner is not, however, limitedin itsapplication solely to oil heating stoves, as my invention contemplatesits use Wherever it may be found adapted.

The aim of my invention, chiefly, is to provide a burner whereby a moreperfect cornbustion will be secured, and whereby a stove may be heatedmore efficiently than with burners heretofore employed.

My invention therefore consists of the, devices and appliances, theirconstruction, combination and arrangement, as hereinafter specified andclaimed, and illustrated in the drawing submitted herewith, which is avertical section through the burner and through adjacent portions of anoil stove.

I carry out my invention as follows:

A represents the shell of a stove, surrounding the tank chamber.

A is a portion of the shell surrounding a hot air chamberA said hot airchamber surrounding the combustion chamber A A is a portion of the shellof the stove located above said hot air chamber and combustion chamber.The upper portion of the stove may be constructed in any desired manner.

B denotes the oil tank or reservoir.

0 0 denote the walls of the wick chamber 0 p B is the supply pipeleading from the oil tank into the wick chamber.

0 is the wick.

D is an interior air flue located within the inner wall of the wickchamber, forming an air chamber D therebetween.

Above the wick chamber I locate perforated air and vapor mixers orcylinders E and E spaced one from the other to form an air and vapormixing chamber E above the wick and between said mixers or cylinders.

F denotes a deflecting drum separating the hot air chamber A from thecombustion chamber A said drum being open at its lower end, andprojecting preferably downward from the horizontal plane of the upperextremity of the mixers E E below the upper end of the wick chamber,forming an air space between the drum and the adjacent portions 'of thewick chamber and mixers, as shown.

Above the hot. air chamber A is located a partition A separating the hotair chamber from the portion of the stove thereabove. Below the hot airchamber 'A is located also a partition or wall A, spaced from the oiltank and extending over the top thereof and downward over the inner facethereof, forming therebetween an angular air passage a, which passagealso extends between the oil tank and the outer case or shell A. As soconstructed the oil tank is exposed to the air at its base, the air flueat extending about its other three sides, thus keeping the tank cool.The wall A separates the \tank from the hot air chamber A The downwardlyprojecting portion of the partition A forms an air space a between itand the adjacent portion of the wick chamber, said air space beingopenat the base, as indicated in the drawing.

It will be seen that between the flue D and the wick chamber is formed acentral airflue a communicating with the air passageD'. The chambers Aand D are closed at their upper ends, as shown at a a so as to deflectthe air rising therein, and compel it to pass through the air and vapormixing cylinders E and E into the chamber E, which is made open at thetop, as shown, for the escape of the products of combustion therefrominto the chamber A thereabove. I prefer also to extend the flue D upwardabove the air and vapor mixer cylinders E E into the chamber A so as tocarry a supply of air into the upper regions of combustion to produceperfect combustion.

It will be evident that the supply of air provided about the oil tank inthe air space a. is deflected under the lower edge of the partition Arising into the hot air chamber through the air space a'. At thesametime air rises independently of the space a into the lower end ofthe space a, as indicated. The air thus rising through the space or fluea' enters the chamber A where it is heated. The escape of the air fromthe chamber A is prevented, except as it is deflected underneath thedrum F and rises within the chamber A and is directed through theperforated cylinder E. All the air entering the air flue a is compelledto pass through the perforated cylinder E. Thus through the cylinders Eand E a large supply of air is directed into the mixing chamber Eaffording an ample supply of air therein at the lower regions ofcombustion. Attention is called to the fact of the location of the twoperforated cylinders above the wick chamber, or so as to supply anabundance of air thereabove. The superior utility of this constructionis obvious.

-What I claim as my invention is- 1. In a stove provided with a hot airchamber, an air and gas mixer within said hot air chamber and openingthrough the top thereof, a wick tube below said air and gas chamber, anda deflector around said air and gas chamber for causing the hot air topass thereinto, substantially as set forth.

2. In an oil stove, the combination with a shell provided with apartition, of an air and gas mixing chamber opening through thepartition, a wick tube below the, chamber, an open ended tube having itsupper end projecting through the partition and its lower 4o endextending down within the wick tube, substantially as set forth.

3. In an oil stove, the combination with a shell provided with apartition forminga combustion and hot air chamber, perforated shellsdepending from the partition into the hot air chamber, which forms anannular space which opens into the combustion chamber, a wick tube belowthe shells and communicating therewith, and an open ended tube extendingfrom the partition down within the inner perforated shell and wick tube,the upper end of which tube extends above said partition, substantiallyas set forth.

4. In an oil stove, the combination, with a shell provided with anannular partition, the inner edge of which is provided with a dependingcylindrical flange, of a hollow wick tube within the flange, the upperend of which is provided with a burner and an oil tank between the shelland the flange and communieating with the wick tube, said tank beingspaced from the shell, the partition and the flange, substantially assetforth.

5. In an oil stove, the combination with a shell provided with twopartitions, one above the other, of a flange depending from eachpartition, two perforated shells, an open ended air tube within the wicktube, and an oil tank between the lower flange and the shell andcommunicating with the wick tube, substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.
